A python wrapper for [rubberband](http://breakfastquay.com/rubberband/).

For now, this just provides lightweight wrappers for pitch-shifting and time-stretching.

All processing is done via the command-line through files on disk.  In the future, this could be improved

by directly wrapping the C library instead.

Install Rubberband on OS X

--------------------------

```

brew install https://gist.githubusercontent.com/faroit/b67c1708cdc1f9c4ddc9/raw/942bbedded22f05abab0d09b52383e7be4aee237/rubberband.rb

```

Example usage

-------------

```python

>>> import soundfile as sf

>>> import pyrubberband as pyrb

>>> # Read mono wav file

>>> y, sr = sf.read("test.wav")

>>> # Play back at double speed

>>> y_stretch = pyrb.time_stretch(y, sr, 2.0)

>>> # Pass rbargs supported in Rubberband CLI. See(rubberband -h or https://breakfastquay.com/rubberband/usage.txt)

>>> y_stretch = pyrb.time_stretch(y, sr, 2.0, rbargs={'-c':'5', '--no_transients':''})

```
